No it's not and we don't. We had a problem with the IRA for many years, but not so much now. The real terrorists are our own government. They are the ones that feed fear, spend all our money on "defence" programmes (plus obscene expenses), weapons, computerize information so anyone can access it, create schools that destroy natural expression and self regulation and teach disempowerment and slavery, change laws as they see fit and generally remove autonomy, free thinking and self assertion as it develops in children and think that our lives belong to them. Nazi Germany is returning and we are too stupid to see it because all the attention in the media is focused on "them" , "the terrorists" , "the threat" or witless TV programmes. Blame. blame, blame. We don't look at ourselves. So why are they doing it? I don't condone terrorism in any way - anger and hate only breed anger and hate - but what a lot of the Middle Easterners object to is how the West focuses on material gain at the expense of millions of lives elsewhere in the world. By destroying the planet just to move money and create fashions, we are creating and allowing enormous suffering and justifying it at every step. That's what they want to change and so the extremists are regarded as heroes in their own country. There is always yours, mine, Monday morning's and the unifying higher truth. The USA is the big perpetuator. They taught the Afghans, The Irish, the Khmer, the South Americans and probably every other major force of oppression. We live so unconsciously that a shake up is an actual wake up call. We need to completely restructure the foundations of our society and take responsibility for the effects we have on the world around us. Yes, terrorism is a big threat, but not how you've been taught to see it. Our own terror which leads to fear, hypocrisy and refusal to look at ourselves is the biggest threat. We create the terrorists. Inner peace is the only way to world peace.
